Investing has a whole new set of rules.

If we are to be successful, we need to play by these new rules.

Why the average equity fund investor underperforms the market?

From 1993 to 2012, the S&P Index 500 averaged a gain of 8.21% per year.

However, during that same 20 year period, the average equity fund investor had an average annual gain of only 4.25%.  

Had the average equity fund investor just bought a low-cost S&P 500 Index fund and held it, he/she would have almost doubled their rate of return.

The underperformance was due to investor behaviour such as market timing and chasing hot funds.

Had these investors been long-term, buy-and-hold investors, they would have earned close to the market's returns.

When the average investor underperforms the index by such a significant amount, it is clear that most are playing with a bad set of guidelines or none at all.

A one-time investment of $10,000 invested at 8% compounds to $46,610 in 20 years.

The same $10,000 invested over the same period at 4.25% compounds to only $22,989.

Short-run performance of the stock market is random, unpredictable and very volatile

The short-run performance of the stock market is random, unpredictable and for most people, nerve-racking.

The next time you hear someone saying that he/she knows how the stock market or any given stock is going to perform in the next few weeks, months, or years, you can be sure they are either lying or self-delusional.

The long-term trend of the stock market is up and its performance consistent

There is more than 200 years of U.S. stock market history and the long-term trend is up.  

Over the long term, stock market performance has been rather consistent.

During any 50-year period, it provided an average after-inflation return of between 5 and 7 percent per year.

If you invested in a well-diversified basket of stocks and left them alone, the purchasing power of your investment would have doubled roughly every 12 years.

Stocks over the long-run offer the greatest potentials return of any investment

Although long-term returns are fairly consistent, short-term returns are much volatile.  

Stocks over the long-run offer the greatest potential return of any investment, but the short-run roller-coaster rides can be a nightmare for those who don't understand the market and lack a sound investment plan to cope with it.  

The 1990s were stellar years for stocks but the 1930s were a disaster.
